h(t) = -16t^2 + vt + 5
h(3) = 131 ft
h(3) = -16(3)^2 + 3v + 5 = 131
3v = 270
v = 90 ft/s
Answer:
584
Step-by-step explanation:
8 + 8 squared + 8 cubed is 8 plus 64 plus 512 which is 584
Answer:
Second choice
Step-by-step explanation:
f(x) = (1/4)(x + 4)^2 - 9
f(x) = (1/4)(x^2 + 8x + 16) - 9
f(x) = (1/4)x^2 + 2x + 4 - 9
f(x) = (1/4)x^2 + 2x - 5
(1/4)x^2 + 2x - 5 =
= (1/2 x + 5)(1/2 x - 1)
Answer: Second choice
Answer:
The answer is (b) cscx
Step-by-step explanation:
∵ secx = 1/cosx
∵ tanx = sinx/cosx
∴ secx/tanx = 1/cosx ÷ sinx/cosx
= 1/cosx × cosx/sinx
= cscx
